C#使用命名管道Pipe進行進程通信實例詳解

1.新建解決方案NamedPipeExample 新建兩個項目：Client和Server，兩者的輸出類型均為“Windows 應用程序”。整個程序的結構如下圖所示。

在這裡插入圖片描述

此Form1為Client的窗體，如下圖所示。

為

後端代碼，如下。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

using System.IO;
using System.IO.Pipes;
using System.Security.Principal;

namespace Client
{
  public partial class Form1 : Form
  {
    NamedPipeClientStream pipeClient =
      new NamedPipeClientStream("localhost", "testpipe", PipeDirection.InOut, PipeOptions.Asynchronous, TokenImpersonationLevel.None);
    StreamWriter sw = null;
    public Form1()
    {
      InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
      try
      {
        pipeClient.Connect(5000);
        sw = new StreamWriter(pipeClient);
        sw.AutoFlush = true;
      }
      catch (Exception ex)
      {
        MessageBox.Show("連接建立失敗，請確保服務端程序已經被打開。");
        this.Close();
      }
    }

    private void btnSend_Click(object sender, EventArgs e)
    {
      if (sw != null)
      {
        sw.WriteLine(this.txtMessage.Text);
      }
      else
      {
        MessageBox.Show("未建立連接，不能發送消息。");
      }
    }
  }
}

此Form1為Server的窗體，如下圖所示

在這裡插入圖片描述

後端代碼，如下。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.IO.Pipes;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Server
{
  public partial class Form1 : Form
  {
    NamedPipeServerStream pipeServer =
      new NamedPipeServerStream("testpipe", PipeDirection.InOut, 1, PipeTransmissionMode.Message, PipeOptions.Asynchronous);
    public Form1()
    {
      InitializeComponent();
    }

    private void textBox1_TextChanged(object sender, EventArgs e)
    {

    }

    private void Form1_Load(object sender, EventArgs e)
    {
      ThreadPool.QueueUserWorkItem(delegate
      {
        pipeServer.BeginWaitForConnection((o) =>
        {
          NamedPipeServerStream pServer = (NamedPipeServerStream)o.AsyncState;
          pServer.EndWaitForConnection(o);
          StreamReader sr = new StreamReader(pServer);
          while (true)
          {
            this.Invoke((MethodInvoker)delegate { lsvMessage.Text = sr.ReadLine(); });

          }
        }, pipeServer);
      });
    }

    private void maskedTextBox1_MaskInputRejected(object sender, MaskInputRejectedEventArgs e)
    {

    }
  }
}

先運行Server再運行Client
